For our TOX®-Powerpackages we offer special solutions. Those are more than accessories and have to be ordered as a complete type of drive. Also the decision of the assembly version has to be made with the design approval.

The new integrated damping option allows an adjustable constant speed of the cylinder working rod during the approach stroke and power stroke, independent of the working forces. Now it is possible to almost fully compensate a stick-slip-effect at a press-in process, and when stamping compensate the sudden acceleration of the working rod when the opposing force is removed.

Press-in applications:

Depending on the application, chattering effects may occur during the press-in operation, the so-called stick-slip effect. This effect induces strongly fluctuating progressions of force/travel making a reliable process control difficult. And this chattering also generates undesirable press-in results and increased noises. With the new damping function ZED, this effect is almost completely compensated. The press-in operation happens controlled at constant speed. The force-travel curves can precisely be monitored and evaluated.

Punching applications:

The break through effect at the end of a punching operation causes an abrupt drop of the counterforce. This results in an instantaneous high acceleration of the cylinder working rod. The punching shock causes high noise levels and premature wear of the tools and the machine. With the new damping function ZED applied, the speed of the working rod remains nearly constant. Thereby shocks are prevented at the end position and noise levels are noticeably reduced.

Advantages:

Damping can electrically be initiated at any point of the stroke

Damping is continuously adjustable

Almost constant speed of working piston

Gentle, monitored press-in of pieceparts is possible

Options:

Speed control via proportional hydraulic valve

Integrated travel measuring system, type ZKW or external version ZHW

The TOX®-Powerpackage with damping ZED can be ordered either with a manually adjustable flow control valve or with a solenoid operated proportional flow control valve.

TOX®-Powerpackage with cutting impact damping ZSD

Accessory for:

EK, AT version .51 or .81

Ideal for dampening in punching applications and for smooth operation of machines during approach or power strokes.

The total stroke is infinitely adjustable. It protects tooling and machine and reduces noise levels.

Advantages:

Hydraulic dampening of end of stroke

Cushioning infinitely adjustable

Total stroke infinitely adjustable

Can be mounted in any orientation

Protects tooling and machine

Reduces noise levels

Maintenance-free

The maximum dampening stroke is approx. 7 mm.

TOX®-Powerpackage with locking brake ZSL

Accessory for:

S, K , X-S, X-K, X-AT

A loss of air pressure will cause the unit to clamp on the cylinder rod. The energy of the drifting or falling load is used to generate the clamping force.

The rod catcher will prevent the cylinder rod from extending unless the static holding force is not exeeded.

The locking brake is kept open by air pressure.

The clamping force increases as the load increases. Internal springs force wedges to clamp the cylinder rod once the air pressure drops. The clamping force is released by applying air pressure and retracting the load.

The locking brake is single-acting.

Special models

Here you find a selection of special versions of the TOX®-Powerpackage perfectly designed for your exceptional application.

Please contact us for any special solutions not found here. There is a large probability that the current, extensive collection of already designed and built TOX®-Powerpackage special executions contain a unit that meets your application. We will gladly check with you all possible alternatives.

TOX®-Powerpackage Type T

Press force:

up to 120 kN

Power stroke:

6 / 12 mm

Total stroke:

6 / 12 mm

The Turbo Cylinder

The "fast" TOX®-Powerpackage with up to 550 strokes per minute. This cylinder is ideal for punching and nibbling machines providing optimum performance. External dampening is recommended.

All TOX®-Powerpackages are available with food grade oil and grease lubrication on request. Both lubricants are certified according to USDA-H11 and are used wherever there is a chance of occasional, technically unavoidable contact with food.

TOX®-Powerpackage ZRO

All TOX®-Powerpackages can be supplied with rust protection on request. All individual parts are either plasma nitrided, galvanised or primed and painted, whereby stainless steel is not generally used. These devices are particularly suitable for use in the food and packaging industries.

Integrated functions

This section lists integrated additional features which can selected when ordering a TOX®-Powerpackage. For several drive types these options are already included as standard.

Power bypass ZHD

Already equipped:

Q-S, Q-K, X-S, X-K, X-AT, S4-S170, K75-K170

Accessory for:

K2-K50

The ZHD is a power bypass with hydraulic end position cushion in return stroke. It provides optimum cushioning of the working piston at the end of the return stroke. This feature is especially useful in applications with heavy tooling weight and high cycle speeds.

In the event of control errors, or in case of special applications, the strong acceleration of the working piston after punching through the material may cause an underpressure in the high-pressure oil chamber of the TOX®-Powerpackage, and so lead to malfunctions.

Additional it is also possible to use the bypass system for the realization of long power strokes.

Power bypass ZLB

The underpressure effected by the strong acceleration of the working piston, can be prevented with the patented TOX®-Powerpackage with integrated power bypass system ZLB.

Already equipped in TOX®-Powerpackages with ZHD

Accessory for: S1-S2, K1

Analog linear position sensor ZKW

Accessory for:

K/AT 2-170, HZL 07-74

The linear position sensor indicates the absolute actual position of the TOX®-Powerpackage working piston. The measuring system works contactless and therefore it is free of wear, insensitive to dirt and interferences.
